Development of tinnitus percept over time (stimulation set 2).

<p>Mean prepulse inhibition change relative to pre trauma response (in percent ± SEM) for non-tinnitus frequencies (open bars) and all tinnitus frequencies (black bars) obtained up to 102 days after trauma, exemplary in four T animals. An impairment of PPI is plotted upward, an improvement downward; significant difference of data to pre trauma is depicted by asterisks in each bar (one sample t-tests vs. 0). Connecting lines indicate significant Tukey post-hoc tests. Significance levels: * p<0.05, ** p<0.01, *** p<0.001.
